Answer:

Amanda's plane flew 59ft

Step-by-step explanation:

So you make simple formulas for this A= Amanda D= Darren and R= Rachel

Darren's is twice as far as Rachel's so D=2R

Amanda's when 19 more feet than Darren's so A=D+19

Then you plug in, you know R=20

D=2R          D=2*20     D=40

A=D+19      A=40+19    A=59
